Nah bro 5000k LED with a HPS would be baller! As would CMH & HPS or MH & HPS...You do realize the 5000K spectrum is for veg and not flower though right?
Would never use anything higher than 3500K if I intended on using it for flowering...
Do you have MH & HPS? Use both next things you flower...You have nothing to lose if it doesn't work to your advantage you still gained information
